  [LLVM] [Support] Query the terminal width using `ioctl()` (#143514)

On unix systems, we were trying to determine the terminal width using
the `COULMNS` environment variable. Unfortunately, `COLUMNS` is not 
exported by all shells and thus not available on some systems.

We were previously using `ioctl()` for this; fall back to doing so if `COLUMNS`
does not exist or does not store a positive integer.

This essentially reverts a3eb3d3d92d037fe3c9deaad87f6fc42fe9ea766 and
parts of https://reviews.llvm.org/D61326.

For more information, see #139499.

Fixes #139499.
